> …that I can trust to issue refunds and discontinue subscriptions promptly. This is a big one. I'm significantly more likely to subscribe to a service/app if I'm able to do so through iTunes, because it means the app developer can't directly reach into my wallet. If I hit "Cancel Subscription" in the iTunes subscription panel, it's canceled, no ifs, ands, or buts, and no hidden unsubscribe links or intentionally obtuse unsubscription processes to have to contend with. This is a huge thing for consumers to give up for the sake of developer freedom. If Apple begins to allow third party payment systems, developers should be required to connect said payment systems to Apple-provided standardized subscription control APIs so strong user control is maintained.
